In some turbine installations, three or more turbines deliver their rate pinions to a sing e'reduction toothed wheel ear driving the pro ller shaft. When there are, for example, our turbines, two pinions with their driving turbines are located on opposite sides of the wheel in, or in the neighborhood of, the mid plane of the wheel, while the third and fourth turbines have to" be mounted above the first two. It is usual to support all of the turbines primarily on the gear casing, either in recesses or on brackets, the free ends of the turbines being supported on cast or forged founda tions.,. This arrangement has the disadvantage that if it is necessary to dismount the casing of the large wheel, the connection between this casingand the turbine casings must be released to enable the upper part of turbines are slipported bya corresponding the gear casing to be lifted. In doing this, it is necessary to change the positions of .the turbine rotors, which positions had revious- 11y been established with considera le care.

11 reassembling the parts, the rotors must be l e-aligned which involves considerable time and expense. 1 y The main object of m invention is to avoid these disadvantages.

accomplish this by providing one or more separate carriers in front of the gear casing, and fixedly secured to the lower stationary part ofthe gearing casing, and detachably secured to the upper removable part. The casings of the upper turbines are supported at one end by these separate carriers, while at the other end, three foundation blo With this arrangement, to dismount the upper part of the gear casing, it is merely necessary to detach the end connection between it and the said separate carriers for the turbines, and to disconnect the couplings between the turbines and the pinion shafts.

Fig. 6'is a view of the form shown in Fig. 5, but with certain of the parts in spaced relationship.

In the construction shown in Figs. 1 and 2, there is a main shaft s-which ma be a marine propellershaft, and which is driven by three turbines. The. two side turbines are not shown, but are connected to the two side shafts r and t. An upper turbine d is connected to the shaft '0. A'reduction eari-ng is providedbetw'een said shafts r, t an o, and

said main shaft 8. This includes a large gear 0 respectively. The gearing casing is formed of two sections a and a uniting along a horizontal dividihg plane Xpassing through the I axis of the shafts.

The turbines are in alignment with their respective shafts r, t and v, and are coupled thereto,

As an important feature of the present invention, a sup ort b is provided, the bottom end of which is fixed to the lower stationary section of the gear casing a, and the upper portion is detachablytsecured to the upper section a', and serves 0 support oneend ofthe casingof the'turbi n d. The other end of-said turbine casing may be "supported by any suitable means, as for instance a foundation block it; For detachably securing the upper section a to the sup ort b, a coupling piece 0 is provided which is secured between said section and said support by, an suitable means, as for instance bolts 0. l inclosing the couplings ,e are separable casing/sec- .tions 0'.

When it is desired to remove the upper gear casing section a to permit repairing or in- 1 spection of the interior of the gear casing,

the shaft coupling casing e .is removed, the

. couplings e unfastened, and the bolt or bolts c which secure the coupling piece 6 to said upper section, are removed. The casing a. may then be lifted without interferingwith the su port of the turbine casing (13, and without a ecting the setting of the turbine shaft. In Fig. 4 is shown a construction in which two upper turbines d are provided above the dividing plane X, these turbines serving to with the large gear wheel It near. the topthereof.

The dismou'nting of the upper section a of the gear casing is effected in the same manner as already described with refere cc to the constructions of Figs. 1, 2 and 3. The

lower turbines may be rigidly connected directly to the ower section of the earing casing as shown in Fig. 5, and have t e casings thereof preferably divided along planes i inclined in the horizontal in order to permit the upper portions of these casings to be removed from underneath-the turbine cas- What I claim is 1.'
